Sensitivity analysis of factors affecting on finite element analysis in soil-tool interaction

摘要: In the present study a finite element investigation of soil tillage process is described using elastic-plastic constitutive material model. For systems, accurately predicting forces acting on blade prime importance in helping to enhance productivity. The properties, such as cohesion, internal friction and Poisson's ratio analysis conditions like mesh density were investigated its effect reaction calculated. A 3D soil-blade interaction was carried out investigate behavior interface properties predicted forces. Results reveal cohesion has significant cutting no Increasing cause an increase accuracy solution time. showed that trend variation with respect tool displacement same at all level independent variables.
